Real Aliens and Alien ContactsThe Possibility of Alien Life

It is possible that a life form technologically advanced enough to travel to Earth might also be sufficiently advanced to exist here undetected. In this view, the aliens have arrived on Earth, or in our solar system, and are observing the planet, while concealing their presence.

Observation could conceivably be conducted in a number of ways that would be very difficult to detect. For example, a complex system of microscopic monitoring devices constructed via molecular nanotechnology could be deployed on Earth and remain undetected, or sophisticated instruments could conduct passive monitoring from elsewhere.

Extraterrestrials may have contacted various humans throughout history, such as Moses and Joan of Arc, to help guide and inspire them to achieve great things.

Or possibly to pass on important messages for humanity; such as a supposed binary message given to a UFO-contactee during the 1980 Rendlesham Forest incident who believes it is the coordinates to a mythical island called Hy-Brasil.

Hy-Brasil is a phantom island which was said to lie in the Atlantic ocean west of Ireland. In Irish myths it was said to be cloaked in mist, except for one day each seven years, when it became visible but still could not be reached.

It probably has similar roots to other mythical islands said to exist in the Atlantic, such as Atlantis, St. Brendan's Island and the Isle of Mam.

The etymology of the names Brasil and Hy-Brasil are unknown but in Irish tradition it is thought to come from the Irish, Breasail, meaning "descendants of Breasal", one of the ancient clans of northeastern Ireland.

Several theories have been proposed about the possible
basis of alien life from a biochemical, evolutionary or morphological
viewpoint.

Alien life, such as bacteria, has been theorized by scientists such as
Carl Sagan to exist in the Solar System and quite possibly throughout
the universe.
No samples have been found, although there is some controversy about
possible traces of life in Martian material, of which the most famous
are on the Allan Hills 84001 meteorite.

The trend to assume that celestial bodies were
populated almost by default was tempered as actual probes visited
potential alien abodes in the Solar System beginning in the second half
of the 20th century.

At the same time, the beginning Space Age was
accompanied by a surge of UFO reports, particularly in the United
States, during the 1950s.

The term UFO itself was coined in 1952 in the context of the enormous
popularity of the concept of "flying saucers" in the wake of the Kenneth
Arnold UFO sighting in 1947.

The moon was decisively ruled out as a
possibility, while Venus and Mars, long the two main candidates for
extraterrestrials, showed no obvious evidence of current life.

The other
large moons of our system which have been visited appear, to our
knowledge, similarly lifeless, though the interesting geothermic forces
observed (Io's volcanism, Europa's ocean, Titan's thick atmosphere and
hydrocarbon lakes) have underscored how broad the range of potentially
habitable environments may be.

Contactees became a cultural phenomena in the 1940s and continued throughout the 1950s and 1960s, often giving lecture and writing books about their experience.

Contactees usually portrayed "Space Brothers" as more or less identical in appearance and mannerisms to humans.

The Brothers are also almost invariably reported as disturbed by the violence, crime and wars that infest the earth, and by the possession of various earth nations of nuclear and thermonuclear weapons.

The possible existence of primitive (microbial) life outside of Earth is much less controversial to mainstream scientists, although, at present, no direct evidence of such life has been found.

Indirect evidence has been offered for the current existence of primitive life on Mars. However, the conclusions that should be drawn from such evidence remain in debate.

The Catholic Church has not made a formal ruling on the existence of extraterrestrials. However, writing in the Vatican newspaper, the astronomer, Father José Gabriel Funes, director of the Vatican Observatory near Rome, said in 2008 that intelligent beings created by God could exist in outer space.

In September 2010, it was reported that the U.N. General Assembly had appointed Mazlan Othman as their official extraterrestrial liaison by the UK paper The Sunday Times. This claim was later refuted.

Theoretical physicist Stephen Hawking in 2010 warned that humans should not try to contact alien life forms.

He warned that aliens might pillage Earth for resources. "If aliens visit us, the outcome would be much as when Columbus landed in America, which didn't turn out well for the Native Americans," he said.

Anthropologist Jared Diamond has expressed similar concerns. Scientists at NASA and Penn State University published a paper in April 2011 addressing the question "Would contact with extraterrestrials benefit or harm humanity?" The paper describes positive, negative and neutral scenarios.

The Search for Extraterrestrial Life

A look at possible extraterrestrial life in the universe; the mission of
organizations like SETI to find it, and the possibility of
extraterrestrial life existing right in our own solar system on the
moons of Europa and Titan.

Search
for Extra-Terrestrial Intelligence (SETI) is the collective name for a
number of activities people undertake to search for intelligent
extraterrestrial life.

SETI projects use scientific methods to search
for electromagnetic transmissions from civilizations on distant planets.

The
United States government contributed to early SETI projects, but recent
work has been primarily funded by private sources. There are great
challenges in searching across the cosmos for a first transmission that
could be characterized as intelligent, since its direction, spectrum and
method of communication are all unknown beforehand.

SETI
projects necessarily make assumptions to narrow the search, and thus no
exhaustive search has been conducted so far. Of course, the first great
assumption is that other intelligent species, whose civilizations could
be hundreds of thousands, or even millions of years old, and so with
technologies far beyond our imagination, use EMR for communication at
all.

Any message determined to be SETI in origin would have to be
decoded. Several tools are available to attack this problem.

We assume
digital data, then try to model the data as either sequential, a 2D
image, or 3D organization.

Sequential data can be analyzed by searching
for repeated patterns, or more complex patterns.

The application
of the Markov process (or the Hidden Markov model) to the deciphering of
SETI messages is centered on the idea of probabilistic relation between
two words.

These symbolic relations can be built into a tree of
probabilities applied to a series of words. Markov Models can provide a
clearer view of the probability of which one symbol will follow another
in a sentence.

Markov Models can be used to build tables of
association of icons or bitstreams. The ultimate goal of these
information theory and cryptographic processes is to decode and
understand the meaning of the message. All the tools contained in
cryptanalysis and information theory can help to decipher the format and
logic behind the symbols but nothing more.

In other words,
these tools may be used to build a list of symbols. Assigning meaning to
the symbols probably requires a combination of linear data and 2D (or
3D, or 4D videos) images. The hope is that the images or videos may be
reconstructed and recognized by a human. Once that recognition takes
place, meaning may begin to be attached to the lexicon of symbols.
